I had a long time on my iPhone 5 a screen protector. An expensive screen protector that I had then bought the same at the Apple Store for the iPhone it. Almost 2 years, I was not really happy with it. The performance of the display was bad, it all seemed slightly out of focus, grainy ..., and also the feeling in use was unsatisfactory. Now I came to this screen protection glasses, a recovered Smartphone another brand, for I by this company for the front - was concerned and the back screen protector glasses, and thought to myself - an attempt is worth it if my iPhone shines so , And lo and behold - it looks beautiful. You see nothing, you just do not see that anything at all is applied to the display. And it touches her as "original" - ie as if you were to use touch screen display without protection. In the photos I've noticed no difference, but I read that there is to be in photos with flash problems with reflections. It is recommended that before applying the protective glass, reproduce long with a CD marker recessed circle for the camera. So the inner ring. I have tried it not because I did not want to take off again the glass after it happens to be attached lint ... Oh yes - Installation: Very easy. Easier than in films. Bubbles, small bubbles can be out emphasize ..., - and lint ... well, there's only a lint-free an environment as possible and rapid application ... strong buy recommendation from me
